Summary: I bought this two and half years ago. I was spending a lot of time in the States and needed a GPS. I bought it because I thought once I got home I could get UK maps for it and fit them on the Hard drive. Now, as others have noted it's discontinued and I can't even get updates for the US, so I've had to buy a Nuvi for UK and Europe and TomTom software for my Phone for US trips.
Summary: It is very unfortunate that you cannot get map updates for this GPS. Overall I found it to be well built, easy to use and efficient. However, I have had the unit for over 2 years. The maps are in serious need of up-dating and there appears no way to do that. There are many places in the country that are constantly changing (Palm Springs, Las Vegas, etc.) On my last visit to Las Vegas this device was practically useless as the map software is so out of date.
